The tap and die sets can get you out of trouble with buggered up threads. As an alternative, there are also “thread chasers”. Thread chasers have edges made for pushing threads back into place as compared to a tap or die which is supposed to cut new threads or shave off bent threads. Practically, you can use and tap/die as a thread chaser, but not the other way around. a company called Lang makes most of the thread chasers in the USA. They are relabeled under multiple brand names such as Lang, Kastar, Craftsman, and Snap-on.

I’ll also second the JIS compatible screwdrivers. The JIS screws are found all over the place and if you buggered up the head of a screw on a Honda, it’s likely that you used a traditional Phillips screwdriver on a JIS screw. I only have three JIS drivers, the +1, +2 and +3 sizes.

This is the style of thread chaser kit I was referring to. It’s got both the file type and the tap/die style:

if you’re working with JIS screws, use either a Japanese screwdriver brand or a screwdriver that satisfies ISO 8764-1 or DIN 5260-PH specs. Using a traditional Phillips screwdriver on a JIS screw is often going to strip out the head of the screw. The modern Japanese/ISO 8764-1/DIN 5260-PH screwdrivers are made to fit both Phillips and JIS screws.

The JIS screws I’ve seen on my 03 CRV … Brake rotors, Door latches, IACV of the throttle body, factory radio come to mind. I’m sure there are many more. Look for that little dot +. next to the screw head, denoting a JIS Screw.

That Posidriv screw head I usually find on IKEA furniture. I ruined many IKEA screws before I knew the difference.

What size JIS are the rotor screws?

They should be JIS +3.

FWIW, if you use a hand/hammer style impact driver, many people say you can get away with using a Phillips style bit. The downward force generated by the hand impact can prevent the cam out that strips the JIS screw heads. (My hand impact happens to have JIS bits)


yes, posidriv and JIS and Phillips are 3 different things. They are three types of screw heads that look similar if you aren’t paying attention. There are more + shaped screw heads out there, just not as commonly seen.
